Specification of Letters Patent.

Patented July 241, 1911"?.

Application iled March 8, 1912. Serial No. 682,351.

To all whom t may concern.'

' Be it known that I, Jnssn citizen of the United States, residing in the city and county of San Francisco, State ofA provide the 'ournal bearing of an axle box with a cham er, in which I place' grease or other suitablevsubstance, and provide a vertical extension adapted to receive a screw threaded plunger with a handle for forcing the lubricating material into the full length of the chamber.

Upon the inner face of the bearing I provide grooves formed parallel with the cham-Y ber just mentioned, and in communication therewith by a series of channels projecting at an angle therefrom through which the lubricating material is distributed upon the journal of the axle.

In the journal box I provide a removable casing which forms the bottom thereof and in which I place a receiver and provide the same with a concave corrugated or otherwise curved face and lupward projecting ends also curved to lit he journal against` which it bears and adapted to receive the waste of lubricant from the lubricating device aboveV the journal, and at' the same time provide means for lubricating said journal at that point and also, suitable means to keep said receiver in position against the journal.

I' also further provide other coperating means to successfully carryl out my invention in practice all of which will be hereinafter described in detail and the novel combination of the various parts which compose the same will be pointed out in the claim at the end hereof.`

'Ihe object I have in view is to simplify the construction of that class of inventions and increase their eiiciency in operation.

-In the accompanying drawings conslsting of one sheet formmg a part ofY the fol .lowing specification I have illustrated my invention in what I believe to be the best C. MARTIN, a

hard grease or a method to carry the same in practice and in which,

Figure 1 isla longitudinal vertical section of the journal bearing box provided Vwith my invention as it appears in position showing also an end elevation or a portion of the axle and the car Wheel thereon.

Fig. 2- is a transverse vertical section along the dottedline :c of Fig. 1 and Fig. 3 is a plan view of the receiver showmg particularly its corrugated bearing face, and in dotted lines a spring means to keep the same in position.

Similar characters of reference denote like parts throughout the several views of the drawings.

Referring to the drawing 1 is the car wheel secured to the enlarged end 2 of the axle A, the journal portion of which 2 bears against the bearing 3 tted into box 4 secured to the. car truck by means of locking guides 5 on the sides of the box.

The box 4 is opened at its bottom in which I place a removable casing 6 secured therein by coinciding bosses 7 Ion the casing and 8 on the vbox at the bottom thereof and a suitable rod 9 passing through the eyes 10 of the bosses as shown in Figs. 1 and 2.

The upper part of the casing just mentioned is opened and therein is the receiver 11 formed preferably of a continuous piece of a sheet of metal or other suitable material if desired and provided with curved projecting end walls 12 fitting the journal portion 2 of the axle and between these walls near the upper part thereof is the corrugated curved surface 13 which forms a series or plurality of receptacles for receiving the drifting lubricant from one side of the journal and spreading or distribute the same upon its other side while rotating.

The'receiver is supported in position within the casing 6 and against the journal 2 by means of preferably a conical coiled spring 14, the largest end of it impinging against its bottom as at 15 and thus providing an even support while the' smallest end rests upon the seat 16 formed on base 17 secured centrally to the bottom of the casing 6 as shown in Figs'. 1 and 2.

Within the central top portion of bearing 3 is the lubricating chamber 18| bored longitudinally and centrally therein and along its length are two series of channels 19 projecting radially atan angle from the sides uli I i thereof which areinte'nded to 'establish communication between the chamber I8 and the grooves 20 parallelly formed therewith upon the inner side ofthe bearing 3 through which the lubricant material is distributed upon the journal.

At one end of the chamber 18 and integrally formed therewith is the vertical upward projecting extension 21 provided with inner threaded passage 22 communicating with chamber 18 and in which the plunger 23 provided with a handle is fitted, asparticularly shown in Fig. 1.

In operation the lubricating material consisting particularly of hard grease is inserted in the chamber 18 in lump pieces through the passage 22 and forced intov the channels 19 by means' of plunger 21 and therefrom into the grooves 20 which are in communication with the axle journal 2 from where the heat generated by the revolving axle softens the lubricant and causes there'- by the same to spread uniformly upon the bearing portion of the axle, and the surplus thereof 'passes into the receiver 11 which becomes an additional means for lubricating the journal.

Believing I have produced novel and useful improvements in that class of inventions and having described the same to enable others skilled in the a'rt to which it appertains to make and use the same what I claim and 'desire to secure by- United States Letters Patent is A journal lubricator, including a box, provided with a bore extending therethrough, a i

lubricating bearing arranged within the box and above the-bore in same, an axle arranged within said bore and being adapted to have the bearing member engage therewith, a cuasing arranged in the lower half of said box and having positioned therein a receiver capable of movement in a vertical plane with A respect thereto, said receiverv being formed yhave hereto set my hand this 1st day of ll/lamb, 1912.
